Hours matter more than year on a mini excavator. At 3,830 this one is past its first set of wear items and nowhere near tired. A mini that gets its hydraulics serviced will run three times that. Ask us for the service history before you decide.
Reach and dig
With the standard stick it digs 10 ft 3 in deep, reaches 17 ft 7 in at ground level and dumps at 11 ft 8 in. The long stick version adds roughly a foot of horizontal reach and a few inches of vertical dig at the cost of some breakout force. Bucket digging force is 8,498 lb, stick force 4,856 lb on the standard stick.
Compact radius
CR means the house barely oversails the tracks. Combined with 80 degrees of left boom swing (55 with the stop fitted) and 50 degrees right, it will trench hard against a wall. Swing speed is 9 rpm.
Hydraulics and travel
Primary auxiliary flow is 15.9 gal/min at 3,553 psi, secondary 7.1 gal/min. That is enough for a breaker or a thumb and not enough for a large mulching head, which is the honest ceiling on this machine. Travel is 2.8 mph high and 1.6 mph low, with 6,921 lb of traction in low. The blade is 6 ft 4 in wide, lifts 15.8 in and digs 18.5 in.
Transport
Shipping height 8 ft 2 in, shipping length 15 ft 8 in, transport width 6 ft 4 in on 13.3 in track shoes. Fuel tank holds 12.2 gallons.
